One feature suggestion for Lemmy someone made: Create something like a multi-subreddit with Lemmy groups .
I love the idea. Basically, you could toss all the fragemented tech topics into a single multi-subreddit, giving you the ability to browse through a single topic but spanning different Lemmy installations.
Oh now that you mention it, a sharable link would be a must. This would promote curated “Awesome…” repos/links.
It would be ideal if it were part of the fediverse naming convention. For example “/m/<multi-subreddit-name>/c/<group1>@<domain1>/c/<group2>@<domain2>/…”
It would allow full transparency, the ability to update / change it… places could even provide URL shorteners for it.
